Irani, who visited a Fabindia store at Candolim two days ago, alleged that it had a CCTV camera focussing at the trial room.
"We will book and punish everybody involved in the case," Inspector General of Police Sunil Garg told reporters here.
"We are examining the CCTV footage retrieved from the store and and all other victims will also be called for recording statements," Garg said.
Four employees of the store who were arrested by the police were yesterday granted bail by a local court which said police had made out no grounds for custodial interrogation.
